v1: - initial implementation (patches 1, 2)
v2: - cleanup, fixes discovered in debug mode
- saner logging
- assertions
- enablement of discard through mount option
v3: - fixed the extent merge loop in discard_atom()
v4: - squashed fix-ups into the main patch (with exception of reiser4_debug())
- fixed bug in usage of division ops discovered while building on ARM
v5: - squashed mount option into the main patch
- refactor based on discussion (see commit msg)
- splitted off blocknr_list code
- replaced ->discard_set with ->delete_set and ->aux_delete_set
v6: - actualized in-code comments
- removed uber-verbose debug statements
- fixed code-to-patch mapping
- moved blocknrlist and blocknrset to kmem_cache instead of kmalloc/kfree
(in a separate commit for ease of reviewing)
- dropped the RFC label
v7: - squashed with PATCHv2 "perform discard before all deallocations"
- dropped extent padding from discard_extent()
- completed in-code comments, cosmetic fixups

Ivan Shapovalov (6):
reiser4: fix reiser4_post_{commit,write_back}_hook() and their invocations.
reiser4: make space_allocator's check_blocks() reusable.
reiser4: add an implementation of "block lists", splitted off the discard code.
reiser4: blocknr_list: use kmem_cache instead of kmalloc for allocating entries.
reiser4: blocknr_set: use kmem_cache instead of kmalloc for allocating entries.
reiser4: discard support: initial implementation using blocknr_list, without extent padding.
